Petrol against the other Alfa Romeo Giulietta versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Petrol | 76.4% | 12,807 |
| Diesel | 68.4% | 12,639 |
| All Alfa Romeo Giulietta | 72.4% | 25,447 |
Why the fuel type changes the number
Petrol cars avoid the DPF and emissions failures that catch diesels, and usually fail on the same consumables as any other car.
On the Alfa Romeo Giulietta specifically, petrol is the strongest at 76.4%, and this petrol version sits 4 points above the 72.4% model average.
What it means if you are buying one
The petrol Alfa Romeo Giulietta is the stronger side of this model on MOT data. Still judge the individual car, but the fuel type is a mild point in its favour. Buying a damaged one? run it through the analyzer, check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average petrol Alfa Romeo Giulietta had covered 71,937 miles at test, against 99,140 for the diesel. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.
Fuel type and mileage are tangled together: diesels are usually bought by higher-mileage drivers, so some of any gap between fuels is the miles rather than the engine. The per-year figures on the Alfa Romeo Giulietta page separate age from fuel if you want to isolate one.
